Good morning
I enabled tracing for Camel in my camelContext.xml file adding the following
trace="true"
I then executed a test with a message I had in another queue.
The file was transmitted and displayed the binary data on the screen.
I do not see any entries in my log file with LOG.trace but what I do see is an
INFO entry when the file was received on the queue and then sent via SFTP and
entry of the following:
BodyType: byte{}
Would this indicate the message/data is being retrieved and sent in binary
format?

Subject: Re: Camel and ActiveMQ SFTP Data Transfers in Raw Binary Format
Thanks for responding so quickly.
The sending application is an appliance, and I have that group validating how
data is being sent along with what connection options and settings are used.
The connection from the appliance to ActiveMQ is performed using the AMPQ
protocol. The data is suppose to be in binary format when it is placed onto
the ActiveMQ queue.
Are you stating that jmsMessageType=Bytes is only valid when data is placed
onto a queue not when read?
Are there any specific trace settings I should set/enable or just trace
everything?
Jason

Hi
When you set jmsMessageType=Bytes then are you sure the sender is sending
the data to the ActiveMQ as byte data?
This option is in fact only for when YOU send messages from Camel to the
broker. Not when you RECEIVE.
You can turn on TRACE logging on org.apache.camel.component.jms
Then Camel will log what kind of JMS message it detected from the broker,
such as
LOG.trace("Extracting body as a TextMessage from JMS message: {}", message);
